Problem flash player vs application-web chrome browser

Hello

We have problem with our application-web in flash / flex since the last update of flash player 27.0.0.130 last week. Our customers use the web application via google chrome and the application works with flash player. It seems to be a display problem. We have 150 users and the problem affects only a dozen users. Here's the problem:

The numbers displays several decimal 0. For example, normally the display is 4.95 $ and at some point the display changes 4.950000000000000. Please See print screen below.

The problem is intermitemps the user logs on using the application all works well. But after 5 to 15 minutes of use the display of numbers changes for numbers with several decimals 0.0000000000000000. The user closes are Chrome browser and restarts it and all return to normal for a period of 10 to 15 minutes. And so on....

We have made no changes to our application lately. Would anyone have a solution to my problem? The user have the problem with windows 7 et 10.

Thanks
